Definitions

  • the present invention relates to bleaching composition for keratin fibres, especially human hair, comprising at least one compound with bleaching and/or highlighting effect and a specific chelating agent.
  • Hair bleaching is a common practice for ages. It is based on oxidative decomposition of hair colour, which is usually done using peroxide or peroxide releasing compounds such as persulfates. Due to highly irritating potential of these bleaching ingredients and dustiness of powder compositions, it is preferred to provide granular composition where dust is reduced by agglomerating small particles into granulates using various binding agents. Most popular binding agent is mineral oil, which was the subject matter of EP 560 088 B1 . Furthermore, EP 778 020 A1 suggests the use of oil and wax compounds or their mixtures for preparation of suspensions.
